GPS Time Synchronization Unit

GPS time synchronization Unit

GPS time synchronization unit – DRM-1010 is a compact DIN rail mountable unit that synchronizes and maintains the timing and frequency requirement of power and process industry equipment using a signal obtained from different external sources such as GPS and GLONASS. GPS Time synchronization unit – DRM-1010 is a cost-effective solution for time synchronization. It provides nanosecond accuracy when external time references are not available. It has a storage facility to store the system log file. It delivers NTP, SNTP, IRIG-B, PFC-Pulse, RS232 & RS485 outputs. The system allows configuration and monitoring through a Web-based application. It supports a wide range of power supply input either 90V-260V AC/DC or 18-36VDC or 36V-72VDC.

GPS time synchronization unit is designed to provide time synchronization to networks such as Electric Sub-Stations, Power Generation and Distribution, Transmission companies, Oil and Gas Utilities, Railways and Metro networks, Airports and Air-Traffic Control facilities, Internet Service Providers (ISPs) and Campus networks. It synchronizes a wide variety of power system equipment – SCADA servers, RTUs, Numeric Relays, Disturbance Recorders, digital fault recorders, Phasor measurement unit, event recorders, Slave clocks, Electronic tri-vector meters, IEDs, Data Loggers and Event Loggers.
